Abstract

The invention discloses a processing method for ancillary facilities of a large-diameter steel cylinder sliced ​​structure, which comprises the following steps: (1) arranging a plurality of tire frames in parallel at equal intervals front and back; (2) dividing the prefabricated steel cylinder into slices The structure is fixed on the tire frame; (3) Position and lay out the wires on the left or right side of the steel cylinder piece structure, and draw the position line of the tongue and groove structure on the surface of the steel cylinder piece structure; (4) Place the wires according to the positioning (5) In the area 4-5m away from the upper top of the steel cylinder slice structure, carry out line measurement, draw a grid, and use a welding torch to weld shear studs on the intersection of the grid; (6) Install cast-in-place concrete formwork. Adopting the method can ensure the smooth processing of the structure on the steel cylinder sliced ​​structure.

Description

technical field [0001] The invention relates to the technical field of processing a steel cylinder revetment structure of an artificial island on the sea, in particular to a method for processing ancillary facilities of a large-diameter steel cylinder slice structure. Background technique [0002] The steel cylinder revetment structure is an emerging technology in the construction of offshore artificial islands. The structure has the characteristics of fast construction, factory manufacturing, and low impact on the environment. It is the key technology to realize the rapid construction of artificial islands. The steel tenon and groove structure in the steel cylinder revetment structure can refer to the structure disclosed in the Chinese patent "Steel Cylinder with Wide Tenon and Groove Device" with the publication number CN104099940B. The steel cylinder bank revetment structure is a large flexibility structure, which requires extremely high quality control during its manufa...
